Abstract

Background: Although different procedures have been proposed as revisional surgery for patients who had previously undergone a failed primary restrictive procedure, the ideal revisional procedure is still a matter of debate.

Methods: A systematic search was performed in all electronic databases to find studies comparing one anastomosis-mini gastric bypass (OAGB-MGB) or Roux-en-Y gastric bypass (RYGB) as revisional bariatric surgery for weight regain or intolerance/complications of a primary restrictive procedure. The data regarding sample size, patients' gender, age, primary surgery type, number of perioperative complications, operative time, pre- and post-revisional body mass index (BMI), and excess weight loss % (EWL%) at 1-year follow-up were extracted. Five studies were included in the analysis.

Results: The primary bariatric procedures were represented by vertical banded gastroplasty (VBG), laparoscopic adjustable gastric band (LAGB) and laparoscopic sleeve gastrectomy (LSG). About perioperative complications, both RYGB and OAGB-MGB showed a similar rate of leaks but OAGB-MGB had a lower rate of bleedings; considering the progression from pre- to post-revisional BMI, OAGB-MGB reveals a better outcome as well as a shorter operative time.

Conclusions: Our meta-analysis has shown OAGB-MGB, used as revisional intervention after failed restrictive surgery, achieves outcomes comparable to RYGB in terms of perioperative complications providing a simpler and more effective technique.

Keywords: Bariatric surgery; One anastomosis-mini gastric bypass (OAGB-MGB); Revisional surgery; Roux-en-Y gastric bypass (RYGB).
